sb driver oops in 2.4.0-test8

Didn't have this problem with 2.4.0-test2, but after upgrading from test2
to test8 the sb driver encounters this error:

Sep 12 20:49:52 wizard kernel: SB 3.01 detected OK (220)
Sep 12 20:49:52 wizard kernel: SB DSP version is just 3.01 which means
                               that your card is
Sep 12 20:49:52 wizard kernel: several years old (8 bit only device) or
                               alternatively the sound driver
Sep 12 20:49:52 wizard kernel: is incorrectly configured.
Sep 12 20:49:52 wizard kernel: sb: I/O region in use.

This is the first sign of trouble. With test2 the message about this being
an old SoundBlaster is usually followed by this:

Sep 11 23:12:28 wizard kernel: YM3812 and OPL-3 driver Copyright (C) by
                               Hannu Savolainen, Rob Hooft 1993-1996

Here is the rest of the oops with test8:

It seems that subsequently applications that use sound hang for a while
and then continue without sound, producing more messages like the above.

This is an ancient 8bit original Soundblaster Pro board. But as I said,
it works with test2 and earlier kernels.
